Final answer:
To find the change in temperature when it drops by 16 degrees Fahrenheit to -16 degrees Fahrenheit, subtract the final temperature from the initial temperature, which shows a difference of 16 degrees Fahrenheit.
Step-by-step explanation:
The question asks how many degrees the temperature is changing when it drops by 16 degrees Fahrenheit to -16 degrees Fahrenheit. This is a simple subtraction problem where you can find the change in temperature by subtracting the final temperature from the initial temperature. If the temperature drops 16 degrees and reaches -16 degrees Fahrenheit, it means the starting temperature was 0 degrees Fahrenheit (because 0 - (-16) = 16). Therefore, the change in temperature is 16 degrees Fahrenheit.
